Part Number: SN65HVD37 Hi team,
My customer is using SN65HVD37DR in their new design.
They recently found that the device's Voh min=2.4V＠Ioh=-8mA, which is lower than the MCU they are using, with Vih=2.7V.
The board is already fixed and there's…

Hi team,
My customer is wondering if they can use this device with half duplex communication. I guess it can't be used for half duplex, it is correct? If it can be used, is there any…
Part Number: SN65HVD37 Hi team.
My customer is designing the layout for SN65HVD37DR.
I guess they have to care about below:
Parallel/equal-length wiring for receiving side A, B and transmitting side Y, Z, respectively.
Receiver A,B and Transmitter…
Part Number: SN65HVD37 Hi Team
My customer have 2 questions about SN65HVD37.
Please kindly help with these. It will be appreciate.
1. Datasheet says VOH(min) is 2.4V on Pin 2(Receiver) when IOH=-8mA.
Customer wants to connect Pin 2 to another…
Hi Adrain,
Thanks for your reply.
My application is to use RS485 for communication between my HMI(Human Machine Interface) and PLC .So i need a protection for RS485 so that my HMI is not affected by any kind of noise or interruption from the PLC while…

Other Parts Discussed in Thread: SN65HVD37 Hi,
I understand SN65HVD37 meets TIA-485-A specificaitons.
So, should the value of Termination be 120Ω ?
In case of SN65HVD37, how much power is Termination(120Ω) consumed ?
Best Regards,
Kato
Brian,
Unfortunately THVD2450 has no full duplex version. In this case, you may want to check out SN65HVD37. Here is an app note showing its performance.
